LANSING - A Lansing man has been sentenced to a minimum of 22 years in prison for shooting a woman to death in early 2017.

Randy Dean Jackson, 57, told police he woke up to find Delores Kay Drouillard dead in her Lansing home and didn't remember killing her. But he accepted responsibility for her death and pleaded no contest to second-degree murder in July.

Jackson on Thursday tried to withdraw his plea in Ingham County Circuit Court, telling a judge he had new information about the case and wanted to go to trial.

But Judge Matthew Stewart denied the request, saying Jackson had provided no details and no legal authority to support withdrawing his plea. He sentenced Jackson to 22½ to 60 years in prison, with 622 days credit for time already served.

Drouillard, 54, was found dead in her home on East Mt. Hope Avenue on Jan. 10, 2017. She had been shot twice in the head. Police recovered a .38-caliber revolver and two spent shell casings from the home. There were no signs of forced entry and no evidence that a struggle had occurred.

Jackson was arrested the next day at his parent's home in Watertown Township, where police also found Drouillard's vehicle.

He told police he stayed at Drouillard's home on the night she was killed. He said he had blacked out from drinking and must have killed her, even though he didn't remember doing it.

Jackson was allowed to plead no contest on grounds that he didn't remember committing the crime. A no-contest plea is not a formal admission of guilt but is treated as a conviction for sentencing purposes.

In October, Jackson and a woman who police described as his longtime girlfriend were charged with embezzling nearly $30,000 from an elderly woman who had let them live in her home in exchange for their help with certain tasks.

The embezzlement charge against Jackson was dismissed in January, but his co-defendant, Mona Liza McKee, pleaded guilty to a misdemeanor embezzlement charge and was sentenced to 25 days in jail.
